High voltage transformer

Abstract

A transformer that prevents breakage of the wire leads thereof. The transformer comprising a generally cylindrical bobbin having a plurality of windings wrapped therearound. Each of the windings has a respective first and second end. Attached to an end of the bobbin is a bobbin endplate having a plurality of first and second end lead breakouts disposed thereon. Accordingly, respective ones of the first ends are attached to respective first end lead breakouts and respective ones of the second ends are attached to respective second end lead breakouts in order to prevent breakage of the windings.

What is claimed is:  
     
       1. A transformer comprising: 
       a substantially cylindrical bobbin;  
       a plurality of windings wrapped around the bobbin, each of the windings having a respective first end and a respective second end;  
       a bobbin endplate attached to the bobbin;  
       a plurality of first end lead breakouts disposed on the bobbin endplate; and  
       a plurality of second end lead breakouts disposed on the bobbin endplate;  
       wherein respective ones of the first ends are attached to respective first end lead breakouts and respective ones of the second ends are attached to respective second end lead breakouts.  
     
     
       2. The transformer of  claim 1  wherein the bobbin endplate is a printed wiring board. 
     
     
       3. The transformer of  claim 1  wherein the second end lead breakouts and the first end lead breakouts are formed from etched copper traces. 
     
     
       4. The transformer of  claim 1  further comprising a core disposed about the windings. 
     
     
       5. The transformer of  claim 1  further comprising an encapsulation layer disposed over the windings. 
     
     
       6. The transformer of  claim 1  further comprising multiple layers of insulation disposed between respective windings. 
     
     
       7. The transformer of  claim 1  wherein each of the first and second lead breakouts comprise: 
       a winding termination pad disposed on the bobbin endplate;  
       a trace segment disposed on the bobbin endplate and in electrical communication with the winding termination pad; and  
       a wire connection pad in electrical communication with the trace segment;  
       wherein each of the wire connection pads is in electrical communication with respective ones of the first and second ends of the wire wrappings.  
     
     
       8. The transformer of  claim 7  wherein the bobbin has a peripheral edge and the winding termination pads are disposed on the peripheral edge in order to facilitate attachment thereto. 
     
     
       9. The transformer of  claim 1  wherein the bobbin has a longitudinal axis and the endplate is attached substantially perpendicular to the longitudinal axis thereof. 
     
     
       10. The transformer of  claim 1  wherein each of the first and second end lead breakouts is staggered outwardly from a previous one. 
     
     
       11. The transformer of  claim 1  wherein the first and second end lead breakouts form a pattern on the endplate to accommodate for increasing diameter of the windings. 
     
     
       12. A transformer comprising: 
       a bobbin;  
       an endplate attached to the bobbin;  
       a wire wrapped around the bobbin, the wire having a first end; and  
       a wire lead breakout disposed on the endplate;  
       wherein the first end of the wire is attached to the wire lead breakout.  
     
     
       13. The transformer of  claim 12  wherein the endplate is fabricated from printed wiring board. 
     
     
       14. The transformer of  claim 13  wherein the wire lead breakout is an etched copper trace of the printed wiring board. 
     
     
       15. The transformer of  claim 12  wherein the wire lead breakout comprises a termination pad, a trace segment and a wire connection pad for facilitating connection of the wire. 
     
     
       16. The transformer of  claim 12  wherein the bobbin has a longitudinal axis and the endplate is attached to the bobbin substantially perpendicular to the longitudinal axis. 
     
     
       17. The transformer of  claim 12  wherein the wire further includes a second end and the endplate further includes a second wire lead breakout for attachment of the second end of the wire.
